Furan Diels-Alder reaction with acrylonitrile

Tetrahydrobenzofurans 173a,b were obtained from the Diels-Alder reaction of 2-(j8-carbethoxyvinyl)furan lh with methyl acrylate and acrylonitrile. [Pg.371]

Furan also undergoes cycloadditions with allenes and even with simpler dienophiles, like acrylonitrile and acrylate (specifically enhanced by the presence of zinc iodide),and with maleate and fumarate esters, if the addition is conducted under high pressure. This device can also be used to increase markedly the reactivity of 2-methoxy- and 2-acetoxyfuran towards dienophiles. Lewis acid catalysis can also been used to accelerate furan Diels-Alder additions. At higher reaction temperatures alkynes and even electron-rich alkenes will add to furan. [Pg.286]
